To understand the difficulties of an ascent to over eight thousand metres, it is enough to remember the almost 300 victims these peaks have claimed. The Swiss alpinist Ehrart Loretan, the third alpinist in the world to have climbed all 14 8,000, and the Austrian alpinist Kurt Diemgerger cover the whole history of the conquest of the world’s 8,000, from the fifties to the present day, together with other alpinists and film directors who have climbed them. They talk about their experienced when they ventured into the death zone.
